Microwindows is an Open Source project aimed at bringing the features of modern graphical windowing environments to smaller devices and platforms. Microwindows allows applications to be built and tested on the Linux desktop, as well as cross-compiled for the target device. Microwindows' genesis was with the NanoGUI project, and has now been combined into a single distribution. The Win32/WinCE API implementation is known as Microwindows, and the Xlib-like API implementation is known as Nano-X.
The Nebula Device is a free multiplatform game engine currently running under Linux and Windows. It uses OpenGL and/or Direct3D for rendering and Tcl/Tk for scripting. Living C++ objects can be browsed and manipulated at runtime from the builtin console, or remotedly from a minimal terminal based console app. A powerful channel animation system allows any floating point attribute to be animated, and specialized animator classes allow things like realtime bone animation with weighted vertex skin.
